EIGRP LAB1

 BSCI 之

EIGRP 官方实验LAB1

 

目标：

1设置基本的EIGRP

2禁用自动汇总

3实现不等价线路的负载均衡

 

本次实验使用的是四台7200。

各个路由器接口配置如下：

R1：

R1#show ip interface brief
Interface                  IP-Address      OK? Method Status                Protocol
FastEthernet0/0            10.1.1.1        YES NVRAM  up                    up     
FastEthernet1/0            192.168.1.1     YES NVRAM  up                    up     
FastEthernet1/1            unassigned      YES NVRAM  administratively down down   
Serial2/0                  192.168.11.1    YES NVRAM  up                    up     
Serial2/1                  unassigned      YES NVRAM  administratively down down   
Serial2/2                  unassigned      YES NVRAM  administratively down down   
Serial2/3                  unassigned      YES NVRAM  administratively down down   
R1#

 

 

R2:

R2#show ip interface brief
Interface                  IP-Address      OK? Method Status                Protocol
FastEthernet0/0            unassigned      YES NVRAM  administratively down down   
Ethernet1/0                192.168.1.2     YES NVRAM  up                    up     
Ethernet1/1                unassigned      YES NVRAM  administratively down down   
Ethernet1/2                unassigned      YES NVRAM  administratively down down   
Ethernet1/3                unassigned      YES NVRAM  administratively down down   
Serial2/0                  192.168.11.2    YES NVRAM  up                    up     
Serial2/1                  192.168.2.2     YES NVRAM  up                    up     
Serial2/2                  unassigned      YES NVRAM  administratively down down   
Serial2/3                  unassigned      YES NVRAM  administratively down down   
R2#

 

 

R3：

 

R3#show ip int
R3#show ip interface brief
Interface                  IP-Address      OK? Method Status                Protocol
FastEthernet0/0            10.1.2.3        YES manual down                  down   
Serial1/0                  192.168.2.3     YES manual up                    up     
Serial1/1                  unassigned      YES unset  administratively down down   
Serial1/2                  unassigned      YES unset  administratively down down   
Serial1/3                  unassigned      YES unset  administratively down down   
R3#

 

R4:

R4#show ip interface brief
Interface                  IP-Address      OK? Method Status                Protocol
FastEthernet0/0            10.1.1.4        YES manual up                    up     
Ethernet1/0                unassigned      YES unset  administratively down down   
Ethernet1/1                unassigned      YES unset  administratively down down   
Ethernet1/2                unassigned      YES unset  administratively down down   
Ethernet1/3                unassigned      YES unset  administratively down down   
R4#

 

 

配置完端口之后配置EIGRP区域：

所需的配置命令示例：

R1(config)#router eigrp 1       / /开启EIGRP区域1
R1(config-router)# network 192.168.1.0 0.0.0.255     / /宣告网段，不宣告的话其他路由器无法得知这个网段

R1(config-router)#no auto-summary     / /关闭自动汇总

 

R3(config)#ip route 0.0.0.0 0.0.0.0     / /在出口设置默认路由

使用VARIANCE命令可以实现不等价线路的负载均衡

注意：如果仅仅在R2的E1/0接口上配置VARIANCE命令，则R2上会显示有两条路径到达R4.但是，R1上只有一条路径到R3！

 

 

拓扑图如下：
